Accurate performance prediction is one of the main concerns in determining the construction time of mechanical excavators such as tunnel boring machines (TBM). A good overview of well-known TBM performance prediction models was published by Farrokh et al. .
Bertha was designed and manufactured by Hitachi Zosen Sakai Works of Osaka, Japan, and is the world's largest earth pressure balance tunnel boring machine, at a cutterhead diameter of 57.5 feet (17.5 m) across.
Navigation of tunnel boring machine at Gotthard General The guidance of a tunnel boring machine (TBM) is comparable with the navigation of a super-tanker: it last long time until the effect of a course-correction will be visible. Skilled machine drivers know the performance of "their" machine in different geological conditions.
Serial entrepreneur Elon Musk says his ambitious tunnel-boring endeavor, aptly named The Boring Company, has officially started digging underneath Los Angeles. Musk announced the news on Twitter, where he said "Godot," the Samuel Beckett-inspired name of the company's tunnel boring machine, had completed the the first segment of a tunnel in the Southern California metropolis.
